I'm a current MS2. Our school will reimburse each student a few hundred dollars for any Step 1 resource we use. We recently underwent a curriculum change: instead of taking Step 1 at the end of second year, we will take it at the end of third year (after completing rotations and we will have a 6 week dedicated study time right after). I see that the three most popular are Kaplan, USMLE-Rx, and UWorld. I heard UWorld is the gold standard.

I'm wondering which Qbank I should use and for how long? I am leaning towards getting the two-year subscription to UWorld Qbank (maybe even the two self-assessments as well) but it's over $600. Or should I just do a 6-month or one year for now, then purchase it again for my dedicated study period? Thanks!
